New description

Coupling between two wagon parts, which are supported with their ends facing one another on a common bogie are

The innovation concerns a coupling between two wagon parts and an intermediate bogie, in which the two viagem parts are pivotally connected to each other by a Drehoolzenverbindungen and a spherical bearing on the Support the intermediate frame.

3 for the articulated car arrangements, oei which have two wagon parts a common bogie are supported, you have to for a Careful transmission of the tensile and braking forces on the one hand and a perfect distribution of the contact pressures, "As technical difficulties often arise"

Such a coupling is already known {US-PS 1 621 91?}, a pivot pin bearing between the two car bodies and a spherical bearing that is between the two Parts of the car body and located on the bogie has. In this coupling, the pivot pin bearing has the same center of curvature as the spherical bearing of the bogie However, since the pivot pin of this device is axially tightly enclosed by cylindrical half-shells, it is indeed a limited swiveling ability of the viagen cases around the pivot pin center axis, but not yours to this possible.

The object of the innovation is to form a coupling of the type mentioned in such a way that the car bodies against one another and are pivotable in different planes with respect to the intermediate bogie.

According to the innovation, this object is achieved in that at the Bolt connection two spherical hinge with adjoining Sliding surfaces of the same radius and the same center of rotation are arranged which form an inner bearing element and an outer shell element, and that the spherical Storage on the pivot pin and the spherical storage on the intermediate bogie have the same center of curvature of their bearing surfaces to have.

The innovation will now be described in more detail with reference to FIG an embodiment described which is illustrated in the drawing. In the drawing show:

Pig. 1 a schematic side view of the coupling between two car parts and a common one Bogie:

Pig. 2 shows a plan view of the coupling according to FIG. 1, sur Half cut horizontally at the height of the coupling along the section line II-II of FIG. 1;

3 shows a vertical axial section through the actual Coupling along section line III-IIT the pig. 4 cut;

FIG. 4 shows a horizontal section through the center of the coupling, in the section line IV-IV in FIG. J;

Pig. 5 shows a vertical cross section through the coupling along the section line V-V of FIG. 4.

The rail vehicle equipped with the coupling according to the invention consists of two wagon parts A .. and Ap, which together are connected via the coupling B and are supported on the common bogie C via the coupling 3 and sliding blocks 3.

At the end of the car part Ap of the vehicle is a central as Rigid connecting element serving eye base i attached with an ■ eye lying horizontally at right angles to the longitudinal axis of the Viagente part, at which two parallel circular disks 2 limit the eye opening of the attachment 1. These two flange-like Circular ring disks hold between them a spherical shell element 4 of the first spherical coupling bearing that represents a ball joint.

This shell element 4 takes the spherical inner element 5 of the Ball joint on, which by means of a socket 6 on a horizontal Bolt 7 is centered between the two fork arms of a fork body 8, through which the bolt 7 passes and on which it can be fixed with a clamping nut 9.

The fork body 8 forms the upper part of the connecting element 8, which is attached to the end of the carriage part A. The lower part 8 _{p of} the connecting element 8 is a spherical dome with the same center 0 as the first spherical bearing or the first ball joint 4, 5; this dome has a sufficient wall thickness and forms the inner bearing element of the second spherical bearing. The circular opening 10 provided in the bottom of the dome S ^ is centered on the vertical axis of the dome,

The cap S ₂ is supported on a spherical pan 11, which forms the outer shell element of the second spherical bearing »In the bottom of the pan 11 is an inwardly upward

protruding sleeve-like cylindrical projection 12 is provided,

the ¹ through the circular opening 10 in the dome 8 ₂ reaches;

the diameter of the projection 12 is considerably smaller than that of the circular opening 10.

A vertical connecting bolt 13 passes through the cylindrical projection 12 and fixes a spherical ring disk 15 arranged within the dome 8 _O over a face plate 14 and a felt disk 16 and thus _{holds the dome 8 2} on the spherical pan 11, although there is play provided is to make the movement of the dome in the pan as easy as possible.

From the description it follows that the first is spherical Storage represents a universal joint between the two carriage parts A and Ap and the second spherical bearing represents a universal joint between the bogie and the wagon part A: the two wagon parts and the bogie can as a result move freely in relation to the other parts around the common center 0 of the two spherical bearings; such Movements are, however, due to the difference in diameter see between the spherical elements 5 and 4 of the first spherical Bearing and the difference in diameter between the cylindrical Projection 12 and the circular opening 10 in the spherical cap 8p limited.

It should be clear that the novelty is not due to the indications of the embodiment of the coupling just described is limited: the details of the embodiment can be modified without leaving the focus of innovation. In particular the innovation is also applicable to a double-coupled Car train made up of N car elements, in the N - i intermediate bogies are provided.
